Oh my goodness, the writing is ridiculously bad.
Bad grammar, odd changes in tense, endless waffling without relevance to the action taking place, logical errors in the plotting, unrealistic characters, repetition… Where was the editor? Or a beta reader?
I am willing to overlook a lot in my popcorn creature features, but I can‘t read this, sorry! DNF at 21%. Yikes.
P.S.: I would be happy for recommendations of some entertaining light horror, set underwater. I have an obsession with caves, diving, etc….
